The dealers would receive prototypes early enough in the spring that they could get some mileage on them and give feedback to the manufactures, these were pre-productions selds. The model as a whole wasn't a protype but the one we had was because we had gotten it in the April of 1999 and put...

They're roughly $200. Definitely worth it if you have the money. It's difficult for me to justify because we can get 10,000 miles out of a set of slides if we have decent snow conditions. Luckily the Polaris profile hasn't changed in a while so you could easily take them off and put them on a...

I feel that Hyperfax are the best slides you could purchase for a snowmobile. DuPont's work better than OEM slides but I don't know if they could hold up to heat as well as the Hyperfax. I'm not too familiar with the Vespel plastic that is used in the DuPont slides but the material used in...

Yea that's me. I don't race, just trail ride so generally I'm in good snow conditions. Good snow allows me to get away with little to no idler wheels. Takes HP to turn wheels! If I start to have slide wear issues I'll run a set of Hyperfax and that'll be the end of it. I'm not sure that...

Yea I'm running a Camoplast 9009H Hacksaw clipped every 3rd window. I had absolutely 0 slide issues this winter and I even removed some idler wheels from the rails, but I'm adding some clips in search of a little speed. The inventor of Hyperfax lives somewhat local to me, in fact he personally...

I already made quite a few changes to my XCR last year, but this summer I'm lowering a set of shocks (different valving/springs), servicing the drivetrain bearings, changing the track clip arrangement and that's about it. As far as clutching goes, I enjoy swapping stuff out, so that's pretty...

It's definitely a lot of work to setup a turbo sled. How many PSI of boost can you run on pump gas? We had a Silber kit on a 2012 pro rmk and it never ran well. Customer didn't have enough money for us to spend time diagnosing the sled so he ended up getting rid of the turbo. He had a stock...

You fabricating your own turbo setup or purchasing an existing kit? We set up a customers AXYS with SLP exhaust, team tied, and our own clutching and the sled runs pretty good. I can't imagine what 180hp+ feels like.

No information other than the fact they're using a sealed connection now instead of just two bullet connectors. This required a new pipe temp sensor and new pipe part# to accept the new sensor since the size of the sensor has changed as well, all information that I got from some engineers at...

iantomasi is in the states right? I wasn't aware that he was doing work on the CFI's, that's good to know. A hot pipe switch is a pretty cool idea, unfortunately the connection for the pipe temp sensor has changed for 2018. Hopefully Polaris isn't using a proprietary connector which would...

I'm new to the forum here. This is my first post so figured I would see if anyone has got some cool summer projects going on with their sleds or if people had some good success this season on some modified stuff. I've got customers curious about big bores. I've read about the Terra Alps 840...
